In an example embodiment, the processor 202 along with the memory 204 and other components of the system 102 may be configured to receive a query from an electronic device 104 (FIG. 1) at the system 102. The querying on the electronic devices 104 is supported by a querying interface, for example a multi-modal querying interface. The querying may be performed by using at least one of or combination of text, sketches and images from one/more users. Alternatively or additionally, in some scenarios, receiving the query may include retrieving the stored one or more previous queries from the system 102. For example, the processor 202 may retrieve a text from the memory and/or data repository 206 of the system 102. One or more functionalities of the system 200 and components thereof, is further explained in detail with respect to FIGS. 3A and 3B.

In one embodiment, the at least one data repository 206 may be a design repository containing a 3-dimensional (3D) model of the object, for example, the 3D model is represented by a polygon mesh. Herein, the object may be a component, or a sub-assembly of components, or an assembly of components. Further, the data repository 206 consists of object metadata which includes information like material, manufacturing and function descriptions for each object and may be stored in the form of a standard ontology. Further, the data repository 206 may contain additional metadata dimensions. For example, the metadata dimension may include but not limited to color, shape, size, material, process, function and manufacture of the object. The metadata dimensions may be identified by an object name or an identifier (ID). The metadata may be three-dimensional representation such as polygon mesh, tree-based representation and the like. The information included in the data repository are part geometry of an object in the form of a 3D model, material definition, manufacturing definition, function description, identifiers for indexing and query and the like.

In an example embodiment, the visualization interface 210 is configured to display multidimensional data of the object. Further, visualization interface 210 is further configured to store the generated multi visualization representation in the form of linked data sets. In some embodiment, the linked data sets may be integrated for creating a shared display amongst the plurality of users. For example, allowing a first user to search the design repository, independently of a second user, from amongst the plurality of users. The first user is alerted of a search of the second user and updates visual representation based on a modification by the second user by accepting and/or rejecting the modification by the first user.

FIGS. 3A and 3B are flow diagram 300A and graphical representation 300B, respectively illustrating functional flow in the system 200 of FIG. 2 for multi-dimensional data representation of an object, in accordance with an example embodiment. Herein, different functional blocks of FIG. 3A and corresponding graphical representations of the functional blocks in 3B will be referred by same numerals to describe the functional flow in the system 200, for the sake of brevity of description and clarity of explanation of the embodiments. Referring collectively to FIGS. 3A and 3B now, in an example embodiment, a query is defined on a device at 302, for example on at least one electronic device 104 (FIG. 1). In an example embodiment, defining the query 302 is performed by sketching at a user interface of the device. As shown in FIG. 3B, a sketch layout 302 implements a canvas for creating a two-dimensional sketch query. In another implementation, the query is defined on the electronic devices 104 by a user by uploading an image onto the sketch canvas. Further, the uploaded image on the device is converted into a sketch-like representation using a neighborhood-based high-pass filter that performs an edge detection. In some embodiments, the electronic devices 104 may also receive the query using textual data to search using the text-query box. Further, a combination of sketch, image, and textual queries may be used for querying.

For the defined query 302, for example a sketch based query, similarity measure is evaluated by comparing the defined query with the plurality of objects stored in the data repository 304 and at least one metadata dimensions as an input provided along with the query. Herein, at least one metadata dimensions may be set as a predefined similarity threshold range based on user preferences. The user defined similarity metrics along with the query is used for evaluating the similarity measure. In another embodiment, the at least one metadata dimension may be extracted from the stored metadata dimensions in the data repository 304. In some embodiment, the metadata dimensions may be extracted based on one or more previously defined queries. Further, similarities between the defined query corresponding to an object is evaluated by comparing defined query with the plurality of objects based on the at least one metadata dimensions to obtain a set of similarity values. Further, the set of similarity values is sorted and a multidimensional array of the similarity values is created. The set of similarity values indicate the extent of similarity between the defined query and the plurality of objects. The similarity evaluation is further described in detail.

As shown in FIG. 3B, at layout 306, a set of similar objects is retrieved and displayed based on the similarity values. For example, ‘N’ matches may be retrieved for the object associated with the defined query from the plurality of objects stored in the data repository 304, wherein N is any numerical value equal to or greater than one.

In one implementation, for the text-query box querying, objects are indexed by labeling with corresponding object name. For example, all the objects labeled as ‘gears’, from amongst plurality of objects that are shaped like the input sketch (query) will be displayed in the layout. The similar object labels are retrieved label matches and the similarity values are displayed. Further, from the set of N similar objects displayed, similar object(s) is selected based on the similarity values displayed 310 of FIG. 3B. In some embodiments, if the similar objects are not matched with respect to a predefined similarity threshold range, the process is repeated by modifying the query and setting the at least one metadata dimension as shown in FIG. 3B. The similarly values and change in a threshold range is further described in detail with respect to FIGS. 4A and 4B. In another embodiment, the objects in the layout falling outside the predefined similarity threshold range is filtered by deselecting from the layout. The similarity between the defined query and the plurality of objects (similarity evaluation) is further described as follows.

In an example embodiment, quantifying similarity between objects, from a plurality of object is performed by evaluating a measure of similarity or a distance between at least two objects. The similarity between two objects is a function of the commonality and the differences the two objects share with respect the at least one object metadata and associated metadata dimension. Further, the similarity of the metadata dimensions associated with the objects are captured using a distance function d: ε×ε→R that operates on elements of a taxonomy ‘ε’ and returns a real valued (∈R) distance measure, that is in in real numbers ‘R’. Herein, the objects are classified as per a taxonomy based approach specific for each of the metadata dimensions.

In one embodiment, the metadata dimension may be material, function, shape and manufacturing of the object, having a material m∈M, a function ƒ∈F and a shape s∈S and manufacturing r∈R. Here, R, M, F, S are the respective taxonomies adopted to represent these dimensions and are considered to be elements of a set ρ. A manufacturing process r∈R is treated as an operator r: ρ×ρ→P such that it operates on a particular object and returns another object with either same or different material and shape properties. Thus the entire sequence of manufacturing processing may be viewed as a composition of operators that transform an initial blank P0{m0, s0, f0} to the final part Pn={mn, sn, fn}.

In an example embodiment, the similarity between the query object and the plurality of objects is interpreted based the metadata dimensions namely material, function, manufacture, and shape, and a set of distance functions is defined for each of the metadata dimensions, namely, dm, df, dr, and ds associated with respectively. The material, manufacturing, shape and function definitions are represented using corresponding taxonomies, a generalized similarity measure may be adapted to the associated taxonomies.

Further, some embodiments may include at least one of algorithms, executable processes, and modules for similarity measure of objects based on a tree-based representation of object metadata. The mentioned similarity measure is applicable for categorical object metadata structured as a tree. The similarity measure generally converts information pertaining to the structure of the tree into a combination of similarity measures for design metadata which may be used to represent the similarity between at least two objects in the data repository.

Further, the computed similarity values are created into a multidimensional array of the similarity values. The multidimensional array of similarity values is a vector of similarity value composed from the dimensions of metadata specified for the collection of objects in the repository. In one embodiment, the array consists of [1-dm,1-df,1-dr,1-ds] where dm, df, dr, and ds represent pairwise similarities between an object and a reference object with respect to material, function, manufacturing, and shape.

In an example embodiment, evaluation of shape similarity using the (Bag of Features) BoF method is disclosed. The shape similarity evaluation includes following steps:

Feature Detection: In this step, a location of interest feature is detected for a given object by computing the “feature points” on the image using the Harris Detector. Detecting said location helps in identifying differences between shapes of at least two objects. The ‘interest feature’ are determined based on one or more characteristics for a particular object.

Feature Description: In this step, a patch descriptors for each detected feature is computed using the Scale Invariant Feature Transform (SIFT). SIFT embeds detected features in a high dimensional space by assigning a dimensional descriptor to each feature. For example, a 128 dimensional descriptors is used. Further, each feature is quantized using visual vocabulary. The feature descriptors computed using SIFT have high dimensionality and the complexity of computation increases with the number of features that are detected. To reduce some of the involved complexity, the visual vocabulary are computed by clustering features in the database, for example, the data repository.

Image Descriptor Generation: In this step, the image data is transformed into a histogram representing a count of occurrences of cluster center matches. Given any two histograms x and y that represent two images Sx and Sy respectively, a p-norm distance can be computed by the following equation:

$d_{s{({x,y})}} = \left( {\sum\limits_{i - 1}^{n}\;{{x_{i} - y_{i}}}} \right)^{1/p}$

In an example embodiment, a simple L¹ norm is used by setting p=1. Additionally, for quick retrieval of similar objects, a fast approximate nearest neighbor method is used to index the queries associated with an object. Thus, the overall distance between two parts is given by a set {dm, d, df; ds}. The set comprises pairwise distances of two objects corresponding their attributes.

The interpretation of similarities in material, function, or any such attribute is largely decided by the context of the application and therefore by the user. Hence, a multi-dimensional array of the similarity values are created, whereby, the user explores the data repository for the similar objects. Further, it also includes overlaying computed similarity information on environmental sustainability value.

The shape descriptor for the query is determined using the BoF method. The descriptor is matched to other pre-indexed descriptors for objects in the data repository and the best ‘N’ matches are chosen. The selected objects, referred here as reference object are displayed in the squarified layout view for further interaction. A probable object is selected from amongst the plurality of reference objects. The probable object is based on the requirement of the query defined by the user and on the predefined threshold similarity range.

Further, based on the similarity values between at least two objects, wherein one of the object is corresponding to the defined query and other object is from amongst the plurality of objects stored in data repository 304, a neighborhood object is determined. The neighborhood object provides any incomplete or missing information about the queried object metadata based on at least one metadata of neighborhood object, wherein the neighborhood is computed using the aforementioned similarity values.

As shown in FIG. 3A, the resulted similarity values are stored in a unit 308, for example, a visualization engine/software, in communication with the visualization interface 310. The visualization engine captures the query defined on the device, interaction amongst the plurality of devices and the information stored in the data repository 304, and displayed via a visualization interface 310. The visualization interface 310 generates multi visual representation (as depicted in 310 of 300B) of the computed multi-dimensional array of similarity values and the object metadata. The visual representations is in the form graphical data including and not limited to a tree-map layout, a bary-centric map and/or a bar graph. Further, the multi visual representation, which is in for example, graphical data, are mapped on to one or more visual variables. In an example embodiment, the visual variables are mapped on to appropriate graphical data using Jacques Bertin's seven basic visual variables: position, size, shape, value, color, orientation, and texture.

Furthermore, as shown in FIG. 3B, the resulted similarity values are further explored using the visualization interface 310, for example, the query is further explored by using a similarity polygon (a) a containing the similarity values, a slider for setting a similarity threshold value (b) and an interactive tooltip (c).

Referring to FIG. 3A, the visualization interface 310 is further configured to allow interactions amongst the plurality of devices to generate a plurality of visual representations, and a plurality of data sets associated with the interactions and to link the plurality of data sets to provide a coordinated multi visualization representation. Further, the interaction between the plurality of data sets is described in detail with reference to FIGS. 5A and 5B.

FIGS. 4A and 4B are graphic representation 400A and 400B illustrating coordination across various windows for computing the similarity values for a pre-defined threshold and change for a change in threshold, respectively, according to an embodiment of the present disclosure. In FIG. 4A, the representation 400A shows various layouts (402, 404, 406, 408 and 410) representing computation of the similarity value in the scalar form of the object. A query is defined in layout 402 (as shown at 402 a), based on which the similar/matching objects are retrieved and displayed in the squarified layout 404. As soon as a user selects an object (as shown at 404 a), namely a probable object, from amongst plurality of reference objects in the layout 404, corresponding 3D viewer is updated at 3D viewer layout 406 (as shown at 406 a). The reference objects are retrieved from the repository for the particular defined query based on the computed similarity values. The object is highlight in the barycentric map of similarity values in layout 408 (as shown at 408 a) and metadata label is displayed in a control window 410 (as shown at 401 a). Similarly, changing the reference object in the squarified layout 404 updates the 3D viewer layout 406, re-computes the barycentric map of similarity values, and displays a metadata label for the reference object with respect to the defined query.

Referring to FIG. 4B, a change in the similarity threshold range in the control window 410 (as shown at 410 b), the background color information in the squarified view is changed, such that the reference object above the threshold are grayed out (as shown at 404 b). Further, the change and effect of these layouts are described in detail in FIGS. 5A and 5B.

In one embodiment the various layouts may be displayed on the electronic devices 104 (FIG. 1). In another embodiment the various layouts may be displayed on a single display screen at the system 102 (FIG. 1).

FIGS. 5A and 5B are graphical representation 500A and table 500B illustrating coordination across various layout of the display with respect to the change and effect in the layout, in accordance with an example embodiment. As shown in FIG. 5A, any changes/modification with respect to the defined query associated with the object, is depicted in the layouts 501, 502, 503, 504 and 505. The changes/modification may include but not limited to changes in selected object, represented in layout 501, changes in reference object represented in layout 501, changes in similarity dimensions, represented in layout 502, similarity sliders represented in layout 502, changes in selected point, represented in layout 503 and query represented in layout 504. Referring now to FIG. 5B, the corresponding effects is shown in table 500B (across the first row of the table). Herein, the corresponding effects are referred with respect to the changes/modification (across the first column of the table). Referring collectively to graphical representation 500A and table 500B, in an example embodiment, the change in object selection 501 will have effect on the object boarder, object label and object layout (marked ‘x’ in the able). Similarly, the change in the reference object 501 will have effect (by updating) on the object boarder, object background, object label, all the points, point color and 3D object and so on and so forth. Various embodiments are as shown in the FIG. 5B, particularly table 500B, depicting various combinations of the change and effect with respect to the object for which the query is defined, reference object and the computed similarity values.

Furthermore, FIG. 6 illustrates collaboration across the plurality of devices, in accordance with an example embodiment. In addition to the display as described with reference FIG. 2, in an example embodiment, the visualization (view) may be on a single display (as shown at 601) containing all the in individual displays or each display on the in visual user device (as shown at 602), the user may interact with each of the individual displays or the coordinated single display.

Further, the system is configured to estimate an environmental sustainability indicator of the objects based on the object metadata and an environmental impact database. When a query is defined for an object, a probable object is selected based on the similarity values, from amongst the plurality of reference objects. Further, the probable object is compared with one or more defined environmental impact characteristics to obtain the probable object which is compatible and sustainable with respect to the environmental impact. The environmental impact characteristics are based on volumetric data of the associated object. The volumetric data includes information related to volume, surface area, convex hull volume, and minimum bounding box volume and unit impact. Further, the sustainability indicator is applied in evaluating the performance metric of the object, for example, entire life cycle of the object.

FIG. 7 illustrates a flow diagram of a method 700 for multi-dimensional data representation of an object, in accordance with the present disclosure. At block 702, incoming query corresponding to an object, is defined on at least one device, for example an electronic device, is received via a multi-modal querying interface. In an example embodiment, the multi-modal querying interface includes sketch windows containing a canvas and related controls for creating/modifying the sketch, uploading an image, and querying the data repository 206 (as shown in FIG. 2). At block 704, a similarity measure is evaluated for a defined query by comparing the defined query with the plurality of objects and the at least one metadata dimensions associated with the object to compute a similarity value. Further, in some embodiments, a text query box is also provided to query metadata dimension. A control panel is used for setting a predefined similarity thresholds for metadata dimensions such as material, manufacturing, function, and shape similarities and combination thereof. In an example, the computed similarity values is in the form of a scalar value. In some embodiments, the similarity values may be pre computed based on one or more previously defined queries on the user devices and stored in the data repository. At block 706, a multi-dimensional array of the similarity values is created. The multidimensional array of similarity values is a vector of similarity values composed from the dimensions of metadata specified for the collection of objects in the repository. Furthermore, in some embodiments, a predetermined similarity threshold range for each of the metadata dimensions is predefined and objects having similarity value outside the range are filtered. The objects are filtered from amongst the plurality of objects based on the computed similarity value i.e., the objects having a similarity value outside a predetermined similarity threshold range for each of the metadata dimensions.

At block 708, multi visual representations of the computed multi-dimensional array of similarity values and the object metadata is displayed. Further, the multi visual representation data are mapped on to one or more visual variable. In an example embodiment, the multi-visual representation generated is in the form of graphical data. The generated multi-visual representation is mapped on to one or more visual variables. The variables are mapped using Jacques Bertin's seven basic visual variables: position, size, shape, value, color, orientation, and texture. The values of these visual variable updates the presentation of data (generated multi-visual representation). In some embodiments, the query corresponding to the object may be defined on a plurality of devices, The method further includes a step of allowing interactions amongst the plurality of devices to generate a plurality of visual representation and a plurality of data sets associated such interactions. The plurality of data sets includes interactions amongst the plurality of devices, a plurality of visual representations and information stored in the data repository. Further include linking the plurality of data sets to provide a coordinated multi visualization representation.

In some embodiments, the above described method is based on query defined on the electronic device by the user and in some other embodiments the method is based on the information such as one or more previously stored queries, user interaction/modification and metadata dimensions stored in the data repository.
